EVENT LOG FILE SCROLLING
The event log file is composed of maximum 100 recorded
events, which include errors, calibration events (type of cali-
bration, date, time) and configuration changes.
To enter the event log file scrolling, press the DISPLAY key
while in normal measurement mode. Event scrolling does
not affect acquisition and transmission of measurements,
which continue normally.
If there is no event in the event log file, nothing happens
when the DISPLAY key is pressed.
Otherwise the primary display will show
the code of the last logged event while
the secondary LCD will show the num-
ber (index) of the event.
For each event the following is reported in any case:
• error code (displayed “Er” followed by the error number)
or setup item code (displayed “S” followed by the setup
item code) or “CALE” indication;
• event index (the oldest event has index 0, the latest event
has the higher index) shown on the secondary LCD.
In addition, the following information can be visualized:
• for errors: • start date
• start time
and if error is not on anymore:
• end date
• end time.
• for configuration changes:
• date of change
• time of change
• previous value
• new value
• for calibrations:
• date of calibration
• time of calibration
• calibrated unit (“pH”, “OrP”, “°C”, “UoLt”)
Once entered the log event scrolling, press the æ or key to
move through the events.
If the event is an error still active, the error code on the pri-
mary LCD will blink, otherwise it will be fixed.
To have a look at the additional information of a selected
event press the key (it will cycle through the additional
information).
Note To exit the log event scrolling, press the DISPLAY key.
Note The logged event information can be downloaded to a PC
through the HI 92500 application software.
